IMPROVEMENT IN DISTR IBUTER TYPE-CARRIERS.

Specification forming part of Letters Patent No. [94,524, dated August28, 1877 application filed January 29, 1877.

To all whom it may concern Be it known that we, WILLIAM A. LORENZ andCHARLES D. HUGHES, both of the city of Brooklyn, in the county of Kingsand State of-New York, have invented a new and useful Improvement inDistributer Type-Carriers, which improvement is fully set forth in thefollowing specification, reference being had to the accompanyingdrawings.

This invention relates to an improvement in type-carriers. The ofiice ofthese carriers, in the various type-distributing machines in which theyare used, is to seize and hold a type till it is removed therefrom by anejector.

In the machine invented by'O. W. Dickinson and W. A Lorenz, to thecarriers of which this improvement is particularly applicable, thetype-carriers are moved, step by step, along a way, resting at eachstep; and while at rest, subjected to the contact of feelers against theexposed edges of the type in the carriers. These feelers select each itsown type from the carriers as they successively pass, and the carriers.must rest at each step in the proper position with reference to thefeelers; and any variation to the left or right may endanger the properworking of the feelers. The carriers are forced along the way, sideagainst side, by pressure applied at one end of the row, the thicknessof the carriers determining the place at which they stop or rest aftereach step or impulse of the machine. Obviously, if these carriers, orany of them, diminish in width by use, to that extent they will fail tocorrespond with the feelers. The type is held against the side of thesecarriers by means of a clutch pivoteda-t the rear end of the carrier,and held against the type when in the carrier, and against the frame ofthe carrier, in the absence of a type, by means of a spring, whichspring must have sufficient tension to hold the type firmly in position,must be as enduring as possible, and must likewise have all theattainable scope.

In the carriers heretofore used the clutch has been held against thetype by aflat spring running longitudinally along the carrier. As thatspring must hold any thickness of type used in the distribnter, it mustnecessarily be made of considerable width and thickness,

and its fast end has to be let into and secured in the rear end of thecarrier, thus materially lessening the bearing-surface of the carrier.Difficulty has attended the use of this form of spring, both from itsliability to fracture, and more especially from the tendency of thecarriers in use to become thinner under constant pressure, chiefly fromthe lack of sufficient bearing-surface. It isevident, when a flat springis used bearing against the outer surface of the clutch, that the sideof the carrier must be left open to allow the fastening of the end ofthe spring to the carrier, and also to allow of the passage of thespring through the side of the frame, so as to obtain the greatest arcof vibration of the clutch with the least width of the carrier.

By this invention a carrier can be constructed with a clutch narrowerand thicker than before, and with a thicker point, while at the sametime the carrier is left with a greater bearing-surface. Theseadvantages are obtained by the use of a spiral spring acting upon theclutch, and from the new construction of the carrier, as will be seenfrom the drawing.

Figure I is a general view of our invention applied to a carrier,without the ejector. Fig. II is a top view of the same, showing moreperfectly the position of the spiral spring. Figs. III and IV are viewsof the clutch and spiral spring.

B is the body or-frame of the carrier, having the clutch A swinging uponthe pivot G. This clutch is acted upon by the spiral spring D, which islet into a recess in the clutch A, and which causes a continuouspressure of its end or finger E against the side of the carrier or thetype when in position.

By the use of this spiral spring, as thus shown, the cutting away of thecarrier side,

which was formerly necessary to allow the fastening and passage of theflat spring, is avoided, and, at the same time, a cheaper, surer, andbetter wearing article is made. The side at G of the carrier B, oppositethe rear end of the clutch A, which was formerly necessarily open toadmit and secure the fast end of the flat spring, is now left solid, sothat our invention leaves nearly twice the bearin gsurface to thecarrier which was before possi- The combination of the carrier-frame B,the ble. vibrating-clutch A, the recess F, and spiral The spiral springD is let into a recess in spring D, by means of which greater scope ofthe clutch, which we mark F.
